SK Functional Polymer (SKFP) introduces Lotader® 4513T for ABS(*) compounds.
Lotader® 4513T is a reactive terpolymer used to improve ABS properties. The introduction of Lotader® 4513T comes as a cost competitive solution to the ethylene/n-butyl acrylate/carbon monoxide (E/nBA/CO) to improve the chemical resistance, paintability and flexibilization of ABS resins. Lotader® 4513T is a heterogeneous terpolymer produced in a tubular process. This heterogeneity generates a higher melting temperature and an improved dispersion into ABS.
SKFP customers have successfully homologated Lotader® in ABS to replace carbon monoxide ethylene modified-terpolymers (E-BA-CO). As the paintability and the chemical resistance are the key properties of ABS compounds in automotive applications, Lotader® 4513T brings a cost-effective solution to carbon monoxide terpolymers. The high methyl acrylate concentration helps to improve the toughness while maintaining good fluidity. This enables the injection molding of complex shapes.
